BAG OR LINING AND METHOD OF PRODUCING THE SAME Filed Jan. 29. 1931 2Sheets-Sheet 2 INVENTOR Edwin D Greene ATTORNEYS Patented May 16, 1933.Lrinkled paper gl nings for containers are usually-madeof, a si ngle.piece of crinkled paper that as foldedover; o'na line extendingaiirthegeneraldi-rectipn of. the crinkles in the paper .with ;the,margins;aof, its longitudinal edgesand the edges pfjoneend folded overand sewed--1 In: somev 'cases,.also the longitudinaledge' iportionjs.ofthe. bag blank either beforeaor.after-closing; the end of the bagtube are tucked in. In using such a bag blank-,as agliningfor;containers, it is opened up or ballooned, usually-by swishing itthrOughithe air: with 'ltSQOpBH end foremost,

and while in open condition is inserted in the container. In the case ofbarrels, kegs and other containers having circular bottoms. it isdiflicult to properly lay the unformed bottom end of the lining on thecircular bottom 1 w of the container, and even where care is exercisedbulky folds are likely to occur at the bottom of the lining which, ofcourse, is objectionable. It has been proposed to form a flat bottom inthe bag blanks or linings before shipment to the user but suchpre-forming of the bottoms adds materially to the expense of thelinings.

One of the objects of the present invention is to provide a bag blankhaving an unformed bottom end which may be easily and 3 quickly insertedin a barrel or other container having a circular bottom so as to closelyfit the container.

\Vith this object in View, one of the features of my invention consistsin the provision of a scoring or crease in the bag blank which is solocated that upon merely ballooning the bag in the usual manner, theclosed 1 end of the lining takes a substantially circular form whichupon insertion of the lining in the container uniformly flattens out andclosely fits the bottom of the container.

Another object of my invention is to provide a lining of the characterindicated of novel and improved construction.

The lining illustrated in the drawings is particularly adapted forbarrels, kegs and other containers having circular bottoms. The bagblank as illustrated'in Fig. 1 may be formed in the usual manner byfolding a sheet of crinkled paper upon itself and folding over andstitching the longitudinal edges as indicated at 2 and similarly forminga. seam at one end of the folded sheet as indi cated at 4. In the formshown in Fig.1 the bag blank is provided with a scoring or crease on aline 6 parallelwith the seam 4 and spaced a distance fromthe seamcorresponding substantially to the radius'of the bottom of thecontainer. The bag blank is also provided with lines ofstitches '8extending diagonally across the coifners the closed end of the blankfron the cr ases;

Owing to the pliability of thecrinkled paper, as the lining is thus opening up, the closed end thereoftends to fiat-ten out from the crease 6, so that when the. bag is readyto be inserted in the container its bottom takes a substantially fiatand circular form, corresponding substantially to the diameter of thecontainer. Also, owing to the lines of stitches 8 the projcct-ingcorners tend to fold over as indicated in Figure 2 so that upon placingthe bottom of the lining on the bottom of the container the cornersreadily lay down flat against the container, and thus a substantiallyuniform fiat bottom is formed in the bottom of the lining which closelytits the bottom of the container.

\Vhile it is preferred to provide the stitches 8 so as to cause thecorners to be folded over easily as the lining is inserted in thecontainer, in place of these stitchings thelinings may be creased acrossthe corners, or if desired the corners may be folded over beforeballooning the bag. In fact it has been found that even without suchprovision for folding over of the corners, that the mere provision ofthe crease 6 assists materially in properly fitting the lining to thecontainer.

In the form shown in Figs. 5 to 10, inclusive, the bag blank isinitially formed in a well known manner by tucking in the longitudinaledges 10 thereof before forming the end seam in the bag blank, and theends of the tucked-in longitudinal portions are stitched in with the endof the bag tube.

In accordance with my invention, a scoring or crease 12, correspondingto the scoring or crease 6, is provided in the bag blank parallel withthe end seam of the bag blank and spaced a distance therefromcorresponding substantially to the radius of the bottom of thecontainer.

During the usual inflation of the bag, the end of the bag blank tends toflatten out from the crease 12 until it reaches a substantiallyflattened condition, and upon insertion in the container it naturallyflattens throughout its area on the bottom of the container as indicatedin Figs. 7 and 8.

As will be evident to those skilled in the art, my invention permitsvarious modifications without departing from the spirit thereof or thescope of the appended claims.

What I claim is:

1. In a. lining for containers of the class described, comprising a flatbag blank of crinkled paper having one end and its longitudinal edgesclosed and having its crinkles extending longitudinally of the blank,the

improvement which consists in said blank, having a peripheral creasespaced a distance from the closed end thereof to assist in forming asubstantially flat bottom in the lining when the lining is opened,said-crease de fining the outer edge of the bottom thus formed and saidbottom being adapted to substantially fit the bottom of the container.

2. A structure according to claim 1 in which the longitudinal edges ofthe bag blank are tucked in.

3. A structure according to claim 1 in which a' line of stitchingextends from said crease diametrically across each of the corners at theclosed end of the bag blank.

4. In a lining for a container having a circular bottom of the classdescribed comprising a flat bag blank of crinkled paper having one endand its longitudinal edges closed and having its crinkles extendinglongitudinally of the blank, the improvement which comprises said blankhaving a peripheral crease spaced a distance from the closed end thereofcorresponding substantially to the radius of the bottom of the containerto assist in forming a substantially flat bottom in the lining when thelining is opened, said crease defining the outer edge of the bottom thusformed and said bottom being adapted to substantially fit the bottom ofthe container.

In testimony whereof, I have signed my name to this specification.

EDWIN D. GREENE.
